Ugh, when did all this HMM specific manipulation sneak into the
generic ZONE_DEVICE path? It used to be gated by pgmap type with its
own put_zone_device_private_page(). For example it's certainly
unnecessary and might be broken (would need to check) to

An upcoming patch changes and complicates the refcounting and
especially the "put page" aspects of it. In order to keep
